Adverse Psychiatric Reactions Information Link (APRIL) is an organization concerned with the adverse psychiatric effects of a wide variety of prescription drugs.

They highlight the fact that everyday drugs commonly used for indigestion, acne, inflammation, pain, infections, cholesterol, malaria prevention and other conditions, can cause serious psychiatric side effects or withdrawal reactions. They argue that long term treatment for perceived mental illness may be prevented if the psychiatric adverse effects are recognised as drug reactions not signs of underlying mental disorders.
